MFJ-1706/1706H 6-Position Balanced Line Antenna Switches
Thank you for purchasing an MFJ
balanced feedline antenna switch. They
provide easy switching of antennas
without swapping wires. They can be used
with any type of balanced feedline and are
rated at full legal amateur radio power.
The model MFJ-1706 uses banana-type
binding posts; the model MFJ-1706H uses
ceramic feedthrough screw terminal
connectors with wing nuts. Both single
and dual banana plugs are available from
MFJ for use with the Model MFJ-1706.
Caution: Use care when connecting balanced feedlines to screw terminals to
avoid short circuits.
TYPICAL INSTALLATION:
Between one balanced-line antenna tuner and several balanced-line antennas.
Connect the antenna connector of an antenna tuner to the antenna switch COM terminals with a
short length of balanced line. Connect the radio connector of an antenna tuner to the radio with a
short length of 50-ohm coax. Connect one balanced line antenna per pair of numbered post on
the back of the switch. The antenna tuner must be adjusted individually for each antenna.
WARNING: Never switch antennas while keying the transmitter.
